The federal health-care overhaul is prompting some colleges and universities to cut the hours of adjunct professors, renewing a debate about the pay and benefits of these freelance instructors who handle a significant share of teaching at U.S. higher-education institutions.

The Affordable Care Act requires large employers to offer a minimum level of health insurance to employees who work 30 hours a week or more starting in 2014, or face a penalty. The mandate is a particular challenge for colleges and universities, which increasingly rely on adjuncts to help keep costs down as states have scaled back funding for higher education.

A handful of schools, including Community College of Allegheny County in Pennsylvania and Youngstown State University in Ohio, have curbed the number of classes that adjuncts can teach in the current spring semester to limit the schools’ exposure to the health-insurance requirement.
